Do elements in group 8 readily or rarely form ions?
Group 8 rarely forms ions since it has steal/lose more electrons to follow the octet rule (having eight valence electrons).
What kind of bonds form when atoms steal electrons?
This is an ionic bond.
In terms of electrons in the periodic table why are group 1 metals very reactive and group 7 non-metals very reactive too?
Group 1 metals are very reactive because they have one electron in their outer shell, which they readily lose to achieve a stable electron configuration. Group 7 non-metals are very reactive because they are one electron short of a full outer shell, so they can easily accept an electron to achieve stability. This makes both group 1 metals and group 7 non-metals highly reactive in order to achieve a stable electron configuration.
Does the number of valence electrons in an atom of an element determines many properties of the element including the ways in which the atom can bond with other atoms?
Yes. The atom only bonds spontaneously if its to become more stable. So depending on the valence electrons, they have different forms of getting that stability. Let's see: Elements from the first and second group have 1 and 2 electrons of valence, respectively, so they tend to give them up. That's why they tend to bond with ionic bonds. They never steal electrons from others. Elements from the 17th group, are missing one electron to have their valence orbitals full, so again, they tend to steal electrons from those of group 1, forming stable ionic bonds. They can also give up some of their electrons, but more commonly they prefer to steal one. Elements like N and C, have their valence orbitals close to 50% filled, so they tend to prefer sharing electrons, that is, covalent bonds. Finally noble gases, have their valence orbitals filled with electrons, so they don't react with anything, and the only bonds they make, are weak Van der Waal bonds between themselves.
What are chemical bonds that steal electrons?
Chemical bonds that steal electrons are known as ionic bonds. In ionic bonding, one atom gives up electrons to another atom, resulting in the formation of positively and negatively charged ions that are held together by the attraction of opposite charges. This process typically occurs between a metal and a nonmetal.
